Founding Product Designer

About Slash Slash is building the future of business banking, one industry at a time. We believe businesses deserve financial infrastructure tailored to how they actually operate. That's why we're creating a new category of business banking. We combine the reliability of traditional banking (high yields, competitive rewards, and comprehensive security) with industry-specific features that make businesses more efficient, more competitive, and more profitable. Started in 2021, Slash is one of the fastest growing fintechs in the world and we power over ten billion dollars a year in business purchasing across numerous industries. We recently raised a $100M Series C led by Ribbit Capital with participation from Khosla Ventures, Goodwater Capital, NEA, and Y Combinator, accelerating our expansion into new markets and products. Slash is headquartered in San Francisco, and has a strong in-person culture. About the role Slash is hiring its Founding Product Designer. This is the first dedicated design hire at the company, and you'll set the visual and product language for everything we build, from the core banking product to the marketing site to how we show up on socials. This role is broader than product design. We need someone who can take a complex financial workflow and make it simple in Figma, and who also has the creative range to art direct a launch, illustrate an idea, or design something with enough craft that it makes Slash look and feel like a company operating at a different level than other fintechs. You'll work directly with our founders and engineering team, with no layers between you and the decisions that matter. What you design ships. What you'll do Own product design end to end. Take problems from our founders, PMs, and engineers and carry them from the first sketch through the shipped product. Set the design system. Establish the visual and interaction language for the core product now, while building the system and documentation that will let a future design team scale it consistently. Direct Slash's visual identity. Take ownership of brand, marketing site design, decks, event graphics, and social content. This is hands-on work: illustration, layout, and original creative, not just applying an existing brand kit. Work in-line with engineering. Pair directly with engineers to prototype ideas quickly, test them, and get real product in front of customers rather than polishing specs that sit in Figma. Use AI as part of your process. Use tools like Claude and Cursor to clarify problems, explore directions, and prototype flows before they reach high-fidelity design. Talk to customers directly. Validate design decisions against how customers actually use Slash, not assumptions about how they should. Build the function you're joining. Set the tools, process, and quality bar that will define how design operates at Slash as the team grows, including a hand in hiring the designers who join after you. What you need Strong product design fundamentals. Interaction design, systems thinking, and the judgment to simplify a genuinely complex financial product without dumbing it down. Real creative range beyond UI. Graphic design, illustration, art direction, or a similar creative background. Your portfolio needs to demonstrate this directly, not just claim it. A track record of ownership. You can point to specific projects you carried from an ambiguous problem through a shipped, successful outcome, not just execution against a defined spec. Comfort operating without a playbook. This role requires building the process alongside the product. You should be someone who is energized by that, not someone who needs it handed to you. Active use of AI tools such as Claude, ChatGPT, or Cursor as part of how you already work. Experience at a fast-growing startup, ideally in a founding or early design role. This is a strong plus, not a requirement, but we're looking for someone who has operated at this level of ambiguity and speed before. Based in San Francisco. Slash has a strong in-person culture and this role is expected in our office.
